FOCALCHECK FLUORESCENCE MICROS EACH，F36913，Invitrogen

The FocalCheck™ fluorescence microscope test slide #2 is specifically designed for calibrating fluorescence microscope systems and evaluating system and filter performance. This slide provides a robust, reproducible method of evaluating the performance of spectral imaging systems, as well as the ability to discriminate closely overlapping spectra. The slide consists of 6 µm-diameter microspheres labeled with a series of spectrally overlapping dyes.
